Abstract

A mobile laboratory is now available to measure toxic compounds in the atmosphere. The mobility of the unit allows access to many sites in the continental United States. When the laboratory arrives at a designated site, a high resolution Fourier transform (FT-IR) instrument is used to measure the toxic materials, or volatile organic compounds, in the atmosphere. The site could be a landfill, lagoon, industrial site, chemical spill or any area where atmospheric pollution occurs. The FT-IR instrument is capable of identifying and quantifying atmospheric molecules at the parts per billion (ppb) level. The path observed by the instrument could be as small as a few meters, or as large as 600 meters in length, nearly 2,000 feet.
